Prof. Dr. Oliver Posegga

Oliver Posegga is the interim Chair of Information Systems and Social Networks at the University of Bamberg, an affiliate of the Center for Collective Intelligence at the MIT Sloan School of Management, and a principal investigator of the project "Communicative Power in Hybrid Media Systems," funded by the Volkswagen Foundation.

His research focuses on understanding the collective dynamics of digitally enabled networks, such as collective behavior and intelligence in organizational and societal settings. In his work, he follows an interdisciplinary perspective bridging information systems research and the social sciences, which is grounded in theories of complex systems, sociotechnical systems, and social networks. Recently, his work has focused on the dynamics of social networks, crisis management, crowdsourcing, data- and information quality, and discursive power in contemporary media systems. 

Oliver received his diploma in Information Systems from the University of Cologne in 2011 and his Ph.D. in Information Systems from the University of Bamberg in 2017. In 2018, he joined the Center of Collective Intelligence at the MIT Sloan School of Management as a visiting scholar. Since 2020, he heads the department of information systems and social networks as interim professor.

His work has been published in peer-reviewed journals such as the Journal of Information Technology (JIT), the International Journal of Press/Politics (IJPP), the Social Science Computer Review (SSCR), and the Business & Information Systems Engineering (BISE), as well as in the proceedings of national and international conferences (e.g., ICIS, ECIS, WI, HICSS, ICWSM, DESRIST).
